I need help with the following assignment below. I have found a similar solution on Chegg and I got the right answers however when it displayed the union for Set A and Set B it listed them as Set A first and then Set B and I need them in numerical order:

Write a Java program that uses one-dimensional arrays to implement finite sets and set operations union, difference, and intersection. Specific requirements:

1. You should name your program as a4sets.java.

2. Elements of a set are integers from 1 to 20.

3. Use 0 as the end of a set. See examples below. 4. Prompt user to enter two sets A and B and calculate A union B, intersection , and A difference B.

Here is a sample input and output: Enter elements of set A: 2 4 6 7 9 0

Enter elements of set B: 1 3 5 7 9 10 18 0 Union of A and B is: 1, 2, 3, 4, 5, 6, 7, 9, 10, 18 Intersetion of A and B is: 7, 9

Difference of A and B is: 2, 4, 6
